ABSTRACT:
A negative electrode for a rechargeable lithium battery includes a current collector and a negative active mass disposed on the current collector. The negative active mass includes a negative active material including a lithium vanadium composite oxide and a crystalline structure aid for inhibiting deterioration of a crystalline structure. The negative active material can inhibit an irreversible crystalline structure change during charge and discharge, and does not incur decomposition of an electrolyte resulting in improvement of a cycle-life of a rechargeable lithium battery.
